Can more information result in less food being wasted? Researchers will be investigating this together with pupils and teachers across the whole of Sweden in the ‘Get wise on food waste’ project. To assist them, they will be using an artificial intelligence app and the world’s largest food sustainability database.
Our food is responsible for over one-third of human-caused climate emissions. At the same time, almost one-third of food produced globally is thrown away. In the ‘Get wise on food waste’ project, researchers are testing a new way to reduce food waste in Swedish schools: by providing more information and feedback to pupils.
Pupils and teachers will be able to see exactly how their food choices and food waste are affecting the climate.
“We hope this can lead to more climate-friendly food choices and less food waste,” said Björn Hedin, a researcher at the Department of Human Centered Technology at the Royal Institute of Technology (KTH) in Stockholm.
An app to calculate the waste
In the ‘Get wise to food waste’ project, pupils can use an app to find out how much food they are throwing away. They photograph their plates before and after eating, and then the app calculates how much is being wasted. Before lunch, they receive information about the day’s menu being served in the school dining hall, the nutritional content of the various dishes and their climate footprint. The information comes from the world’s largest database on factors relating to food and environmental impact, health and justice, developed by the company Consupedia in collaboration with researchers at Dalarna University and KTH.
Creating virtuous circles through feedback
Through the project, researchers want to test whether it is possible to create virtuous circles in how food is dealt with – from wholesalers through to pupils. Making pupils more aware of how their food is affecting the climate, health and the environment, can lead to more thoughtful choices in the dining hall. As school kitchens get better information about what food their pupils like and dislike, menus can be adapted to better suit the needs of the pupils. The kitchens can then make more tailored orders from the wholesalers, so that the amount of waste is reduced both in school kitchens and at wholesalers.
We hope that as many schools as possible will take the opportunity to join the ‘Get wise to food waste’ project and carry out research to create a sustainable future. The more pupils that participate, the better results we can get.”

Citizen science for a sustainable future
The’ Get wise to food waste’ project is an example of citizen science, whereby researchers enlist the public’s help to address issues that they cannot investigate on their own. For pupils, it is an opportunity to participate in real research, while teachers get access to research-based material to incorporate into their teaching.
“In our previous citizen science projects for schools we have seen that pupils really appreciate doing something that is actually ”real”. In the ‘Get wise to food waste’ project, they are helping to develop new knowledge that can be used to tackle a current societal challenge,” said Fredrik Brounéus, a Researcher and Press Officer at VA (Public & Science).
The ‘Get wise on food waste’ project (‘Svinnkollen’ in Swedish) is being carried out between 27 April and 15 May 2020 and is a collaboration between Dalarna University, the Royal Institute of Technology (KTH), the company Consupedia and the non-profit organization VA (Public & Science). The project is being funded by the Swedish Energy Agency and Consupedia.
